IMPROVEMENT IN TENONING-M'CHIYNES.

Specification forming part of Letters Patent No. 116,089, dated June 20, 18,71.

To au whom it may concern:

. Be it known that I, GEORGE W. PAssEL, of the city of Cincinnati, in the county of Hamilton and State of 0hio,-have invented certain new and useful Improvements in Tenoning- Machines, of which the fcllowing is a specilication:

My invention consists in an adjustment for giving lateral motion to the cutter-heads of a tenoning-machine and their operating-shafts, when said shafts are belted at the side of the machine, opposite to which the cutter-heads are located.

In the accompanying drawing, towhich reference isher'eby' made, Figure l is the front elevation of machine embodying my invention. Fig. 2 is a side elevation, and Fig. 3 is a plan of the same.

A is the fra-me of the tenoningfmachine. B B are the front faces of this frame, made smoothv and straight. C C are frames which slide vertically upon B B', and are secured to B B by devices, as I) D', overlapping the sides of A. C and C slide independently of each other, and are elevated or depressed by a separate suitable device. The shaft M revolves in the jour- 'nals H H attached to the sliding frame C. E

is a secondary frame sliding laterally in frame C,and secured to C by suitable devices. (See Fig. 2.) P is an arm of the frame E, elevated enough to clear the pulley N. Through the end of .this arm, which is bent back ata right angle to main part of the arm, passes a screw, T, turning in a socket in the arm P,vwhile its thread engages a female screw in a shoulder,

R, of the frame C. This screw is operated by a hand-wheel, W.v The .journals H H are attached to frame E, and contain the bearings in which shaft M revolves. K K are the cutter-heads, operated by their respective shafts.

K is attached to shaft M, and K -to shaft M'. 'Y

N is a pulley attached to thatend of shaft M opposite to where cutter-head K is, and operating shaft' M. Nl is a pulley attached to that endof shaft M opposite to where cutter K is and operating shaft M. Neither of these pulleys is between the journals of its respective shaft, but are beyond said journals. It is apv parent that this arrangement ofthe pulleys givesthe operator double the space he has hitherto had for operating the machine, and no longer crowds him u-p against the cutterheads and timber while raising or depressing the vertically-sliding frames.` The belts also
